Performance Parameters
- Timers: Includes two 16-bit timers and a watchdog timer.
- Interrupt Handling: Supports 4-level requesters, 7-level interrupters, and 7-level interrupt handlers.
Material Composition
Constructed with high-quality electronic components and industrial-grade multi-layer PCB, ensuring long lifespan and high reliability in harsh industrial and military environments.
Structural Characteristics
Standard 6U VME module size. Integrates DRAM arrays and various interface controllers on the front panel or board, communicating with the backplane via P1/P2 connectors at the rear.
Operating Principle
The MC68030 main processor and MC68882 coprocessor work collaboratively to handle complex floating-point operations and logical control, transmitting processing results at high speeds to other system modules via the VME bus.
Installation Requirements
Ensure the VME chassis is equipped with a forced air cooling system (typically requiring 10 CFM airflow) to guarantee heat dissipation for high-power-density integrated circuits.
Usage Precautions
Regularly check the status of the on-board backup battery to ensure data in non-volatile RAM and the real-time clock is not lost after power-off. Avoid operating without shielding in environments with strong electromagnetic interference.
